Co- and Post-seismic Crustal Deformation Associated with the 2016 Kumamoto Earthquake Sequence Revealed by PALSAR-2 Pixel Tracking and InSAR

This archive includes the dataset for the co- and post-seismic displacements associated with the 2016 Kumamoto earthquake in Japan detected by ALOS-2/PALSAR-2 data. All files are formatted as the MATLAB format. ALOS-2/PALSAR-2 level 1.1 data in this study were provided from the PIXEL (PALSAR Interferometry Consortium to Study our Evolving Land Surface) under a cooperative research contract with the Earthquake Research Institute, University of Tokyo. The ownership of ALOS-2/PALSAR-2 level 1.1 data belongs to JAXA.

coseismic_datav1.mat contains the original PALSAR-2 pixel tracking data and 3D displacement components. You can display 3D displacement field using "display_3Ddisp.m".

coseismc_flocv1.mat contains the isolated displacement discontinuities in the observation data.

postseismic_asc_v1.mat contains the PALSAR-2 original InSAR data in the ascending orbit.

postseismic_dsc_v1.mat contains the PALSAT-2 original InSAR data in the descending orbit.

script_acrossp_p.m generates the profiles of post-seismic displacement profile across the profile.

script_alongp_c.m generates the profiles of co-seismic displacement along the fault.

script_alongp_p.m generates the profiles of post-seismic displacement along the fault.

script_quasi_def.m generates the quasi-eastwest and the quasi-vertical displacement fields.

script_ts.m generates the time-series of line-of-sight change using the sequence of InSAR data.

display_3Ddisp.m displays 3D displacement fields using "coseismic_datav1.m".

coseis_Fdisp.mat contains data for along-fault displacement. (Lon, Lat, vertical, stv_vertical, horizontal_alongfault, stv_horizontal_alongfault, and topography)

display_coseis_alongdisp.m generates figures for the along-fault displacement distribution using "coseis_Fdisp.mat".
